It originates in the Nueva Vizcaya municipality of Aritao, where the Santa Fe River joins the Marang. It is the largest tributary of the Cagayan River by discharge volume of water, with an estimated drainage area of {{convert|5,200|km2}}, roughly twenty percent of the total drainage area of the Cagayan River.

==Tributaries== The following are the tributaries of the Magat River by length: *Alimit River – {{cvt|99.4|km}} *Matuno River – {{cvt|84.7|km}} *Ibulao River – {{cvt|78|km}} *Taotao River – {{cvt|61.1|km}} *Santa Cruz River – {{cvt|54.8|km}} *Padol River – {{cvt|38.5|km}} *Lamut River – {{cvt|38|km}} *Santa Fe River – {{cvt|33.6|km}} *Benay River – {{cvt|30.1|km}} *Marang River – {{cvt|28.4|km}} *Manga River – {{cvt|28.3|km}} *Balasig River – {{cvt|21.4|km}}

==Magat River Integrated Irrigation System== The Magat River Integrated Irrigation System Project, started by the National Irrigation Administration in the 1960s, is one of the Philippine's largest irrigation projects with hydroelectric power generation capacity. Its total cost amounted to US$500 million.<ref name="nwin"> {{cite web|url=http://www.nwin.nwrb.gov.ph/Prog&Proj/JICA/studies/water_usage/MagatRiver.htm |archive-url=https://web.archive.org/web/20111005122601/http://www.nwin.nwrb.gov.ph/Prog%26Proj/JICA/studies/water_usage/MagatRiver.htm |url-status=dead |archive-date=October 5, 2011 |title=Magat River |publisher=National Water Information Network |accessdate=October 24, 2008 }} </ref>

The project is made up of the Magat reservoir, three diversion dams, a large number of irrigation canals and three pumping stations to supply irrigation water for an area of about {{convert|97400|ha|km2}}. It is also includes hydroelectric power plants; {{convert|360|MW}} at Magat reservoir, {{convert|6,000|kW}} at Baligatan and {{convert|2,500|kW}} Magat mini-hydroelectric power plants in Maris main canal.
